Model reduction for dynamic real-time optimization of chemical processes

The value of models in process industries becomes apparent in practice and literature where numerous successful applications are reported. Process models are being used for optimal plant design, simulation studies, for off-line and online process optimization. For online optimization applications the computational load is a limiting factor. The...

Dynamic Optimization in Business-wide Process Control

The chemical marketplace is a global one with strong competition between man- ufacturers. To continuously meet the customer demands regarding product quality and delivery conditions without the need to maintain very large stor- age levels chemical manufactures need to strive for production on demand. In this thesis we research how market...

Model-based optimization of the operation procedure of emulsification

Emulsions are widely encountered in the food and cosmetic industry. The first food we consume is an emulsion, namely breast milk. Other common emulsions are mayonnaise, dressings, skin creams and lotions. Equipment often used for the production of oil-in-water emulsions in the food industry consists of a stirred vessel in combination with a...

Structured controller synthesis for mechanical servo-systems: Algorithms, relaxations and optimality certificates

In many application areas of mechanical servo-systems the high demands on the performance often imply a tightly tuned feedback controller, that takes dynamical interaction into account. Model-based H-optimal controller synthesis is a well-suited technique for this purpose. However, the state-of-the-art synthesis approach yields controllers with...

Model-based lifecycle optimization of well locations and production settings in petroleum reservoirs

The coming years there is a need to increase production from petroleum reservoirs, and there is an enormous potential to do so by increasing the recovery factor. This is possible by making better use of recent technological developments, such as horizontal wells, downhole valves and sensors. However, actually making better use of these improved...
